System and method for optically communicating information between a display and a camera |
摘要 |
A system and a method for optically communicating information between a display and a camera that is observing the display. In general, the transmission of information is unidirectional in a direction from the display to the camera. The display transmits information to the camera that is observing the display by displaying a series of symbols and images (such as an alphabet) on the display. Information (such as a network address of the display or camera) may be transmitted to the camera without any prior shared knowledge between the two. The present invention also is capable of determining a spatial location (or pose) of the display (relative to a camera observing the display) by observing a pattern presented on the display and using well-known correlation techniques.
